摘要

#CMT# #/CMT# The structure has a ceiling recess (7) that guides the door leaf (2) into top recess (6) housed above the wall opening (1). The wall recess (3) and ceiling recess are closed by a cover flap (10). The pivoting movements of wall flap (9) and the cover flap are executed according to the triggering of retaining device (11) so as to open the path of the door leaf. The retaining device (4) is coupled with wall flap, cover flap and door leaf. #CMT#USE : #/CMT# Fire protection sliding gate structure installed in building. #CMT#ADVANTAGE : #/CMT# Since the pivoting movements of wall flap and the cover flap are executed according to the triggering of retaining device so as to open the path of the door leaf, the fire protection function of the sliding gate structure can be improved even when power failure occurs. The sliding gate structure is simple. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of the fire protection sliding gate structure. 1 : Wall opening 2 : Door leaf 3 : Wall recess 4,11 : Retaining device 6 : Top recess 7 : Ceiling recess 9 : Wall flap 10 : Cover flap.
